DAVID L. s'riLns, OE' ROUHESTER NEW YORK' IM PROVEMENT IN COOKINGSTOVES- Specification forming'part of Letters Patent No. 37,778, dated February 24, 1863.

.To all whom t may concern: Be it known that I, DAVID L. STrLEs, o Rochester, in the conntyof Monroe and State of New York, have invented a new and lmproved Mode of Gonstructin g Cookin g-Stoves; and l do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a vertical section of the stove, showing the oven, on the line x m of'Fig. 2.

Fig. 2 is a perspective view of the oven with the top. and front plates removed. Fig, 3 is a perspective vview of the oveu'with the top and back plates removed. Figlis a 'section on the line y g/ of Fig. l. Fig. 5 is a detached perspective view` of the ventilatin'g tubes and thimbles t' k.

'Likel'tters designate corresponding parts firechamber, and U the throat or large fine.-A

space directly underneath the oven. Here the heated column is divided, and ascends in equal portions up the front and back sides of the oven. Each of these columns is again divided in front by the inclinediiue-plates or partitions b I), Fig. 2, which deliect the ascending currents and force them to the extremeupper and outer corners of the oven-those portions which they usually fail to reach fullyand on the back by similar partitions, d d, which differ from the former only by terminating before their lower ends meet, in order toA leave space for the damper c. The columns ot" air which ascend'these front and back dues meet on the top ofthe oven, but are caused to return by the'two partitions f j', which carry the heated air partially down the front and back sides.

between the' inclined partitions b b and d d until those fines unite in the central space, g,

which communicates with the smoke-pipe` IL..

ovens-viz., the imperfect heating ofthe ends and corner portions, those which, from their spent by pursuing the tortuous course of the fines, a-nd afterward passed around the central portions of the oven, (whichnot being exposed to cold air, does not lose its heat. so rapidly), and thus the heatis equally distributed- Eto all parts. The' damper c, when open, allowsy theheat to pass directly to the smokepipe when the oven is not use d.

l am aware that stoves have been constructed 'which take the heatedair up at the corners and'down through the descending fines, returning it under the bottom but these do n't fully accomplish the object of my invention,as the current of hotfair cannot be made to fully penetrate the angles without being deflected 'to those points. Besides,V the arrangement of those to which I allude is complicated, requiring a damper in front, and the lower or fire portion ot' the stove must be constructed to correspond with the dues of the oven portion. This is not the case with mine, as all theA iiuedivisions are contained in the oven portion, the throat C, below, being only a single capacious area, which lessens the expense of construction considerably, and enables the oven portion to be used on any other stove of suitable .size with the same effect.. 1t also pos-y sesses the advantage of placing the iineplates and damper'so far from the intense heat of the re that they are far more durable than in other stoves.

The front inclined flue-plates, b b, are so constructed that they can be drawn up, as represented by dotted lines in Fig. 2, to allow the dust and ashes which accumulate above them to fall into the space below, where itis removable. They are supported by flanges which allow them to lmove readily. A

In all tlucs surrounding stove-ovens there is a constant accumulation of dust and ashes, which, in those having vertical fine-partitions, readily falls to the bottom, where it can be conveniently removed; but where the'flues are much inclined, the deposited dust remains where it falls, seriously obstructing the fines by diminishing their area. This would be the case with the front fines of my stove it' provision were not madefor clearing them by rais# ing the movable partitions ylrb, whereby the inno' oven. The top ofooch Que-nimo b projects by thmportion of tbopmtition which oxtonds upon tho top of the oven, and is provided with s hoi@ by moans of which arrangement it irony easily be soizod by tho hand or by any hoo'krdinsirn motor. inserted through bailo holes in cho iop of the oren and tho objoot aooompiishd Airis admitiod just bao'k of ino ino-chamber into a oondnoting-spaoo, fm. by which it is carried 'ireory under ho oren, Whore it branohes in @ber direction and discharges 'ihiougii small tubes int-o the int'orior of 'the oren.
